IMPROVEMENT IN GAS-GOVERNORS.

Specification forming part of Letters Patent No. [68,55 l, dated October11, 1875; application filed December 11, 1874.

To all whom it may concern Be it known that I, SiLns D. BALDWIN, of thecity ot' Chicago, in the county ot' Cook and State of Illinois, haveinvented certain new and useful Improvements in Gas-Grovernors, of whichthe following is a full de scription, reference being had to theaccompanying drawings, in which- Figure l is an elevation; Fig. 2, avertical section; Fig. 3, a bottom view of the upper section, and Fig. 4a vertical section of the cap enlarged.

This invention relates to gas-governors, having for its object toimprove the same; and consists in the combination of the sections,interior passage, and diaphragm, which serves as a packing, as will behereinafter more fully set forth. i

In the drawings, A represents the upper half or section of agas-governor, B, the lower half; a, the diaphragm; b, the valve-stem; c,the sharp valve-seat; d, the valve; e, the gas passage; f, theregulating-screw, g, the gaspipe, .and h the burner. a: y is an openingfor large governors, to be used in the place ot' lthe screw f in thesmall governors, which are made a part of the gasburner.

In constructing a governor of large size, to be applied to the pipes,the only change desired is the change from the screw f to the opening or1, which is made large enough for the introduction of weights to heplaced upon and regulate the diaphragm, and closed with wax and aseal-cap, so, asshown at Fig. 4.

In the form shown the governor is made a part of the burner, and in thisformythe opening and cap o0 1/ are not required or used.

I make the governor in two sections or hemispheres, as shown, andprovide them with tlanges, so that they can be riveted or boltedtogether, and hold the diaphragm in place.

The diaphragm a is stretched across and between the hemispheres A B, asshown at Fig.2. At the center there is suspended from this diaphragm a avalve-stem, b, by suitable collars and screws, at the lower end of whichis placed a conical valve, d, which vibrates up .and down, according tothe pressure on the its permanent sticking, and prevent the re-L tainingof lthe tar on the valve-seat.

In order to start the valve, in case it should by any means becomestuck, I provide the governor with the screw f, by which the valve canbe pressed down so as to start it, or keepv it permanently open, ifdesired, and also to regulate the extent of the lifting of thediaphragm. This screw may be so inserted asto come in contact at itslower end with the metal oi' the valve-stem, if desired.

The gas-passage e is formed by boring or drilling a hole through a smallportion or' the metal left on the inside of the chamber, as shown, ahole being made in the diaphragm to correspond with the holes in themetal. By this arrangement I take the gas around the upper or airchamber without taking it outside of the governor.

The burner h may be made of any of the known forms, and the device isattached to the gas-pipe in the usual manner.

By this arrangement I make a governor which is simple in itsconstruction, and which is efficient in its operation for a very longperiod ot" time.

What I claim as new is as follows:

l. The combination of the sections A B and the interior gas-passage cwith the diaphragm a, serving as a packing for the sections andgas-passage, all constructed and arranged substantially as specitied.

2. The combination of the self-sealing eapopening as y with agas-governor, substantially as specified.
